Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones. The

The crushing capacity of one of these mills varies from 850 lbs. to 1400 lbs. per 24 hours, according to the hardness of the rock. It is to be specially noted that the crushing is performed quite dry. I tested the degree of fineness to which these mills reduce the quartz by differential siftings of a number of samples, taken by spoonsampling the heaps of crushed ore lying at various mills
